- CytroCell: a computational study in aqueous solution and infrared spectroscopic structural characterizationPublication . Tixier, Anne-Sylvie Fabiano; Michel, Nicolas; Ciriminna, Rosaria; Petri, Giovanna Li; Angellotti, Giuseppe; Pagliaro, Mario; Garcia, AnaA COSMO-RS conductor-like screening model for realistic solvation and molecular dynamics simulations conducted in GROMACS were used to gain insight into the structure and behaviour of CytroCell citrus nanocellulose in aqueous and more complex solutions, including the green solvent dihydrolevoglucosenone. DRIFT spectroscopy was used to investigate the structure of CytroCell nanocellulose solid samples obtained via acoustic cavitation of lemon, orange, and red orange industrial processing waste. The computational and experimental results obtained are relevant to all forthcoming applications of this new family of nanocelluloses sustainably sourced from the citrus industry’s main waste product via the CytroCav circular economy process.
- Structural features of highly bioactive citrus integroPectin revealed by x‐ray diffraction, fourier transform infrared, and nanoparticle tracking analysisPublication . Ciriminna, Rosaria; Angellotti, Giuseppe; Petri, Giovanna Li; Valenza, Chiara; Mauriello, Francesco; Nuzzo, Domenico; Picone, Pasquale; Girgenti, Antonella; Sano, Caterina Di; D’Anna, Claudia; Pagliaro, Mario; Garcia, AnaCitrus IntegroPectin denotes a family of flavonoid-pectin bioconjugates with large therapeutic potential sourced via the green extraction CytroCav process consisting of cavitation of industrial citrus processing waste conducted in water only, followed by dialysis and lyophilization or spray-drying. We investigate the structure of lemon, orange, and red (blood) orange IntegroPectin using X-ray diffraction, infrared spectroscopy, and nanoparticle tracking analysis. The analysis unveils several structural nuances unique to this new class of bioconjugates of relevance to forthcoming studies on the use of citrus IntegroPectin for therapy and prevention of numerous diseases.
